Batman is the best there is..

none can.. coz if u look at each one of them.. they are one way or the other dependant on their powers/ abilities, take tht away.. u take out half the threat.. on the other hand.. batman doesnt depend on anyone/anything but himself.. no superpower/ no super ability.. if u look at the 4 of them .. they are in a way vulnerable at a point.. but nt batman..
